When a model view is created without materialize: true on S3 data,
the table listing and preview were previously showing the error: unsupported duckdb datatype: "NULL" instead of the actual exception.

• Table listing view: No tables were shown only error unsupported duckdb datatype: "NULL".

This issue will be resolved once we move to the new listTables implementation (base PR).
In that version, errors will no longer occur during listing — they’ll only be raised when fetching table metadata (column name, and data type). As a result, only the affected table will report an error.

• Table preview: Will now display the actual DuckDB error instead of the generic “unsupported datatype” message.
